To all whom t may concern:

Be it known that I, Emi. Fnuns, of Ithaca, in the county of Tompkins and- State of New York, have invented a certain new and useful Safety Mechanism for Breakdown Guns, of which the following is a specification.

My invention has for its object the production of a particularly sim le and eilicient safety mechanism for break own guns; and

it consists in the combinations and constructions hereinafter set forth and claimed. In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views. Figure 1 is a longitudinal sectional view of a portion of a gun equipped with my safety mechanism. Fig. 2 is a. plan of a portion of the trigger plate and contiguous parts.

1 is the frame, 2 are the barrels pivoted at 3 to the frame, and 4 is the foreend of a break-down gun. 5, 6 and 7 are, respectively, the hammers, sears and triggers of the tiring mechanism of the and sear springs which are not illustrated may be of any suitable construction.

10 is the thumb lever ofthe means for locking the barrels and frame together and normally preventing the brealng of the gun. The locking means also includes the usual catch which coperates with a rearwardly extending lug 12 onthe barrel, and also a sliding bolt 13 movable in a horizontal guide extending lengthwise of the frame and 'into and out of anotch or recess 14 formed in the depending barrel lug 15. The bolt is suitably connected to the thumb lever 10, and is here show nas formed with a slot 16, Fig. 2, in which works'an'eccentric 17,

Fig. 1, provided on thevertical lspindle 18 upon which said thumb lever is mounted.

Y holding the bolt 13 in its retracted or unlocked position, this means being' automatically operable by the barrels to vrelease the bolt as the barrels approach their normal or As'here illustrated, said closed position. means comprises a spring-pressed catch 20 movable in a vertical guide 21 formed inthe x gun. The main the rear frame 1 beneath the horizontal guide for the bolt 13, and opening into said horizontal guide. This catch 20 is movable by a spring 22 lnto the horizontal .guide for the bolt 13,

in front of a depending shoulder 23 on said bolt, and 1s rovided with a partproiecting into the pat of the barrel lug 15 in order to be engaged and depressed by said lug to move the upper end of the catch out of the path of the shoulder 23 for permitting the bolt 13 to be moved forwardly into the recess M of the barrel lug 15 by the spring 19, as said recess 14 moves into registration with the guide for the bolt 13.

The catch 20, as here shown, comprises a central body and a flange at the lower end of the body, the body being formed 'with a central recess 24 opening through its lower end face, and in which the spring 22 extends, and the liange 25 isannular in form and a portion thereof projects into the path of the arrel lug 15. Said flange 25 also engages contiguous parts ofthe frame t limit the movement of the catch20. The lowerl end of the spring 22 bears againstthe removablevtrlgger plate 26 and the catch is arran d so that it is .removable upon the detaching of the trigger plate. Y

The locking means shifts the safety mechanism of the gun into position to prevent the operation of the tiring mechanisms, and as here illustrated the safety mechanism Vin-V -cludes a longitudinally movable member 27 arranged between the tiring mechanism and having laterally extending shoulders28 normall engaging upwardly-facing surfaces 29 on t e'trlggers for preventing the operation of' the triggers, the member 27 having its front end arranged in the path of the bolt 13 and itsrear end engaged by a slide 30 arranged on the u per tang 31 of the frame. Said member 27 1s supported by front. and

Vrear pairs of lugs 32,33 projecting upwardly from the removable trigger plate, airof lugs 33 en ging Aopposite sides of e member 27, :inflat-he front pair of lugs 32 forming pivotal supports for the tri ers 7 and engaging the outervfaces of sai triggers, the triggers being arranged on o posite sides of the member 27. Y Both pairs o? the lugs 32, 33 arev provided with pinsi extending through slots 35 formed 1n said Y member 27, the pin 34 carried by the front pair of lugs 32 serving as the pivot for the triggers 7. The safety meinber- 27 isalso formed with angularly arranged arms 36 and 37 extending upwardly-at its front and rear ends, the front arm 36 projecting into the path of the rear end of the bolt 13, in order to be en aged and gushed rearwardly by the bolt, w en said bo t is being shifted to unlock the barrels, the movement rearwardly of the member 27 carrying the shoulders 28 into engagement with the upwardly facing surfaces 29 of the triggers 7 and thus lockin said triggers. The rear arm 37 of the saety member 27 is engaged by a fork 38 engaged with front and rear faces of said arm 37 and rovided on the slide or fingerpiece 30, and) consequently when the lingerpiece 30 is moved forwardl the fork 38 and the arm 37 move the sa ety member 27 forwardly to carry the shoulders 28 out of engagement with the upwardly facing surfaces 29 of the triggers and into alinement with the cutouts or slots 39 in the triggers, and thereby release said triggersfrom the safety member. Obviously, when the n is broken the triggers will be automatically locked from movement.

The trigger-plate is detachably connected to the frame at 40 as by the screw 41 so that when the plate is detachedthe triggers and safety member will be removed therewith and the arms 36, 37 of the member 27 disengage themselves from their coacting parts 13 and 38 during the removal of the trigger plate.

The hammers and cocking members shown herein form the subject matter of my application, Sr. No. 528,855, filed November 19, 1909, and this application is a division of said application.
